That depends on the kind of longevity. - If it's "stay old longer" then yeah, that's a problem (most of our present advances are this since they don't address ageing, just save people from its consequences). - If it's "stay young longer (or indefinitely)" that will change a lot of assumptions. But it might also make people put off children until really late, like, "if you're less than 100 why are you even considering being a parent?"

Stay young longer is SF, stay old longer is already happening.

  "Stay young longer" is healthy lifestyle and a bit of personal responsibility.

    Basically the problem of ageing is a gradual accumulation of "damage" of assorted kinds. An ideal regimen of exercise and diet and non-stressful life and so forth can reduce the rate but not to zero. Thus, even healthy people get old and die. Actual therapies would go in and undo the damage, not stop it accumulating, but clean the existing damage down to a level where ageing symptoms would be reset back by decades. And could be repeated, leading to indefinite lifespans.

      Yes, of course, I agree with you. However, the quote I was replying to had the word "longer", and not the word "forever" in it. And that's exactly what healthy lifestyle gives you - not miracles, but a definite increase in quality of life, and prolongation of the active part of it. The downvotes to my comment above amused me, there are apparently people in denial here. :)

  Stay young longer is near-future and clearly-approaching tech. It won't be one magical longevity treatment, it will be a number of closely linked medical breakthroughs and resulting therapies in stem cell replenishment, senescent cell clearing, amyloid clearing, etc. Many of which are in the pipeline, not clinical yet, but active research. Google: the SENS research foundation.
